Abstract: Disclosure is made of a method for electronic polar attenuation of torque profile for positive displacement pumps by a processor where the attenuated torque profile is compared with the shaft displacement angle of the pump input shaft. The processor then signals a motor to power a pump with the result of pumping at a constant pressure at the full range of the designed system flow volume. In addition to the attenuated torque profile, the processor can also account for the response time of the pump drive, the motor inductive reactance, system inertia, application characteristics of the pump, and regenerative energy during deceleration of the pump.

Abstract: An electrical submersible well pump assembly has a SAW (surface acoustic wave) sensor on a motor shaft. A SAW electronic circuit mounts to the motor housing. The SAW electronic circuit has an antenna closely spaced to the SAW sensor for monitoring torque on the motor shaft. A controller at an upper end of the well supplies power to the motor. A motor gauge unit mounted to a lower end of the motor transmits signals to the controller. A signal line extends from the SAW electronic circuit to the motor gauge unit for transmitting signals from the SAW electronic circuit to the motor gauge unit, and from the motor gauge unit to the controller.
